We indeed are living through an occult renaissance, although not in this completely baffling way — we’ve made a ton of progress in understanding the mechanics of ritual (Victor Turner, research in cult psychology, as well as Ernest Rossi’s research into the mind-body connection).
To approach magic as anything else than culturally framed approach to practical philosophy is no more, no less, but a fallacy.
A much more viable approach would be to engage such thinkers as Bem and Radin, replicate the experiments, run statistical analyses on everything. The CIA recently uploaded some interesting documents on telekinesis and remote viewing — apparently they had quite a bit of success with these methods.
Besides, why would anyone do magic (witchcraft, ceremonial, whatever your flavor is) at all, when it’s so much easier to simply talk people into stuff (if we want to influence them), or take whatever actions are best if we have a goal we want to attain?
Mystical praxis, at its very core, is little more than just another approach to therapy, having the goal of complete personal integration.
Of course, the claim could be made that metaphysical concepts have a real, direct impact on our lives, however I don’t believe approaching it through outdated, and frankly misguided, frameworks is a good idea.
